proportion is 21/25
Since d is being subtracted from bc, we first add d to each side. Now we are left with a + d = bc.
Since b is being multiplied by c to be bc, we divide both sides by c.
We now have a/c + d = b
Your solution is: b = a/c + d
32. 5^-2=1/25
5^-1=1/5
5^0=1
5^1=5
5^2=25
5^3=125
The domain are -2,-1,0,1,2,3,
The range are 1/25,1/5,1,5,25,125
So as the domain increases so does the range
Answer:
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Assume θ with a value and substitute with it.
Let θ = 45°
So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2
R.H.S = cot θ = cot 45 = 1
So, L.H.S ≠ R.H.S
So, sin θ cos θ = cot θ is not a trigonometric identity.
<span>6-t/2t+9 = -2
multiply both sides by 2t+9
which will give you
6-t= -2(2t+9)
6-t = -4t + 18
now add 4t to both sides
6 -t + 4t = -4t -18 + 4t
6 + 3t = -18
6-6 + 3t = -18 -6
3t = -24
t = -24/3
t= -8 (negative 8)
